Teen star Lindsay Lohan is fed up with the press only being interested in her wild social life because she's desperate to be taken seriously as an actress.

The 18-year-old actress is enraged that her fellow actresses Keira Knightley and Scarlett Johansson - both just two years older than her - are highly praised for their work, whereas she's known for her relentless partying and troubled family life, reports the Internet Media Database.

She has signed up to work with Meryl Streep on the upcoming movie from legendary director Robert Altman, the film version of "A Prairie Home Companion". "It's hard for me to have to watch (Knightley and Johansson)," she said.

"I work just as hard as those people and sometimes (the media) make it seem that they're more mature because their fan base is more mature and my fan base is younger. So they're writing about me going out all the time. I'm a young kid and I have a lot of pressure... (but) I know work is work."
